Side, which is 7 km away from Manavgat, is an ancient settlement center. Side, which is mentioned by historians as being founded in 1405 A.D., had been ruled by the Lydians, Persians, Alexander The Great, Antiogonous and Ptolemaioses respectively, beginning from the second half of VIth century A.D. After 215 A.D., the city, which had improved greatly under supervision of Syrian Kingdom, turned into a scientific and cultural center in the process. Having been left to the Bergama Kingdom as a result of the Apameian peace, the city later protected its independence along with the Eastern Pamphilya region. The city soon flourished, gaining tremendous wealth and prosperity with a huge commercial fleet.

The main gate of the city, which has an unique labor, lies between two towers. There are two main streets in the Side province. These streets are typical examples of the columned streets from the Ancient Age. After passing city gate, the flat stones adorned area is the starting point of this street. There are columned porticos beside both sides of these streets, and shops behind them.
